Implement Windows Support

[duosii]

previous PR

I have implemented Windows support by making the following changes:

• Listen for CTRL_C signal in daemon listener.
• Use pg_ctl to start and stop the PostgreSQL server on Windows.
• Implemented a Windows Unit Test workflow.

For the time being, I have disabled the test_tempdb_bin_path and test_slow_postgres_startup tests on Windows due to their reliance upon bash scripts.
I have also removed the Python unit test as I was unable to get this working on Windows.

Have you had the chance to review this pull request yet?

Or is Windows support something you don't want to add to pgtemp?

I could close this PR if that is your wish.

Hi, I was really busy in august and must have missed this entirely, sorry about that.

I have two reservations:

1. I don't have a windows machine to help test or debug this if someone has an issue
2. I don't necessarily trust the tj-actions installation action. The first thing that came up when I googled it was that it was compromised in May of this year.
